What is the value of the expression? (5 1/4 - 2 1/2) + (6 2/3 - 3 1/2) Enter your answer in the box as a mixed number in simplest form.

71/12

Step-by-step explanation:

(5 1/4 - 2 1/2) + (6 2/3 - 3 1/2)

(21/4 - 5/2) + (20/3 - 7/2)

(11/4) + (19/6)

66/24 + 76/24 = 71/12

if this is really you s much. i only have 3 points left and i have 2 questions to ask

5x + 3y = - 4

step-by-step explanation:

the equation of a line in standard form is

ax + by = c ( a is a positive integer and b, c are integers )

express the line first of all in slope- intercept form

y = mx + c ( m is the slope and c the y-intercept )

to calculate m use the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (7, - 3) and (x₂, y₂ ) = (4, - 8)

m = = -

y = - x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (4, - 8 ), then

- 8 = - + c ⇒ c = -

y = - x - ← in slope-intercept form

multiply all terms by 3 to eliminate the fractions

3y = - 5x - 4 ( add 5x to both sides )

5x + 3y = - 4 ← in standard form
